In 2025, the budget smartphone market offers many models with decent performance for a reasonable price. To choose an inexpensive device that won’t lag, it’s important to consider key features such as RAM size, processor, type of internal storage, and screen refresh rate.

  1. RAM: At least 6 GB

For smooth operation in 2025, a smartphone needs at least 6 GB of RAM. Models with 3 to 4 GB can no longer handle modern apps, causing lag during multitasking or when launching heavy programs like messengers, games, or editors.

Why it matters: 6 GB allows you to keep 5 to 10 apps open at once, switch between them quickly, and run games on medium settings.

Bonus: Some models support virtual RAM (storage-based expansion), adding 2 to 6 extra GB.

  1. Processor: MediaTek Helio G99 or better

The chipset is the heart of the smartphone. It determines speed, battery life, and even camera performance. The minimum level for a budget device is the MediaTek Helio G99 (6 nm, about 400,000 points in AnTuTu v10), which ensures stable performance in games like PUBG and Call of Duty on medium settings, as well as everyday tasks.

Alternatives:

  • MediaTek Helio G99-Ultra: A slightly overclocked version found in Xiaomi and Infinix models.
  • Qualcomm Snapdragon 685 or 695: Comparable performance with better graphics (Adreno 619) for gaming.
  • MediaTek Dimensity 6020 or 6080: Support 5G and offer better energy efficiency.

What to avoid: Helio G35 or G85 and Snapdragon 680 — outdated chips with weak performance.

  1. Internal storage: UFS 2.2 or higher

Storage speed affects app launch time, game loading, and video recording. In the budget segment, UFS 2.2 is the best choice (read/write speed around 1200/500 MB/s).

Why it matters: UFS 2.2 is two to three times faster than outdated eMMC 5.1, which is still used in the cheapest models.

Recommendation: Choose smartphones with 128 GB storage (or 256 GB for photo and video storage) and a microSD slot supporting up to 1 TB.

  1. Screen: Refresh rate of 90 Hz or more

A 90 Hz or higher refresh rate ensures smoother animations, scrolling, and gameplay. It doesn’t directly affect performance but greatly improves the user experience.

Optimal setup: IPS or AMOLED with 90 to 120 Hz and Full HD+ resolution (2400x1080).

AMOLED advantage: Brighter colors, deeper blacks, and lower power consumption.

What to avoid: 60 Hz displays, which look choppy compared to 90 Hz.
